Question

Causes of viscosity

Answer 1

Viscosity is a principal parameter when any flow measurements of fluids, such as liquids, semi-solids, gases and even solids are made. Brookfield deals with liquids and semi-solids. Viscosity measurements are made in conjunction with product quality and efficiency. Anyone involved with flow characterization, in research or development, quality control or fluid transfer, at one time or another gets involved with some type of viscosity measurement.

.

.causes:

Intermolecular force of cohesion

Molecular momentum exchange

.

.

Due to strong cohesive forces between the molecules,any layer in a moving fluid tries to drag the adjacent layer to move with same speed ,producing effect of viscosity.

.

.

The individual molecules of fluid are continuously in motion and this motion makes possible the process of exchange of momentum between different moving layers.

Answer 2

HEY MATE HERE IS YOUR ANSWER


VISCOSITY IS CAUSED BY THE COHESIVE FORCES BETWEEN THE MOLECULES IN LIQUIDS, AND BY THE MOLECULAR COLLISIONS IN GASES.
